"The ground in almost every part of it is covered with stools or stems of Oak, at not more than three feet stool from stool, and these not having been thinned since last cutting, are completely overburdened, and are evidently killing each other and dying for want of nourishment […]"

"With stool bedding, the plants are pruned back to the ground in the dormant season, and the shoots that form in the spring have juvenile characteristics and are called "juvenile reversion shoots." Stool bedding or stool bed layering is a common practice for the production of rootstocks of apple. […] The closer the apical meristem is to the roots of the plant, the more juvenile it is likely to be. This feature is exploited by techniques such as hedging or stool bedding that employ severe pruning to decrease the distance between the new growth and the root system, thus acting to rejuvenate the plant and benefit from the ease of rooting that is characteristic of the juvenile phase."

"A coppice may be large, in which case trees, usually ash (Fraxinus) or maple (Acer) are cut, leaving a massive stool from which up to 10 trunks arise; or small, in which case trees, usually hazel (Corylus), hawthorn (Crataegus), or willow (Salix), are cut to leave small, underground stools producing many short stems. […] One consequence of coppicing is that the stool enlarges because each subsequent growth of shoots occurs on its outside. The diameter of a stool is thus directly related to its age. […] stool 1. A tree stump that is capable of producing new shoots. 2. The permanent base of a *coppiced tree."
